Advantages and key features:

1. 1.Independently driven caterpillars using vector motors. They allow a constant pulling power. Furthermore, they reduce energy waste and the number of moving parts subject to maintenance.
2. 2.Long caterpillar contact length assures a good grip on the pipe and provides considerable pulling power.
3. 3.Caterpillars bow profile. The shape reduces stretching and wear of the caterpillars, thus prolonging the life of the machine.
4. 4.Pivoted upper caterpillars which feature a pipe crushing control system.
5. 5.Motorized positioning of lower caterpillars that can be adjusted according to the diameter.
6. 6.Chain conveyors with neutral rubber pads on chains that do no mark the pipe.
